SPEOlFICATION formingV part of Letters Patent No. 686,447, datedNovember 12, 1901. Y l Application tiled August 277, 1901. Serial No.73,458. (No model.)

T all whom it mag/concern:

Be it known that we, FRANK Fmrscn, Jr., JOSEPH EnrrscH, and WILLIAMFRrTscH, citizens of the United States, residing at Sedro Woolley, inthe county of Skagit and State of Washington, have invented a new anduseful Fly-Trap, of which the following is a specification.

The invention relates to improvements in 1o iiytraps- The object of thepresent invention is to improve the construction of y-traps and to inthe accompanying drawings, and pointed out in the claims heretoappended. Y

In the drawings, Figure 1 is a perspective view of a fly-trapconstructed in accordance with this invention and shown applied. Fig.'

5o 2 is a longitudinal sectional view of the same. Fig. 3 is a detailsectional view on the line 3 3 of Fig. 2.

Like numerals of reference designate corresponding parts in all thefigures of the draw` ss iDsS- 1 designates an oblong receptacle designedto be arranged vertically adjacent to lthe pane of a window-sash, asillustrated in Fig. 1 of the accompanying drawings,and provided withinner and outer transparent walls 2 and 3, consisting, preferably, ofplates of glass arranged in ways et of opposite sides o f the uprightcasing 1. The casing l is supported by a rod V5, secured by screws orother suit- 4 5 able fastening devices to the receptacle at one sidethereof and to the sash 6 at the top of the same.

The receptacle 1 is provided with an opening '7, formed in one of thesides which support the 5o plates of glass, and secured to thereceptacle at the said opening is a horizontal casing 8,

provided with transparent sides 9 and having a transparent top 10. Thecasing is provided with a suitable frame which supports the transparentwalls, and t-he bottom of the casing is preferably constructed of wood.The casing forms a passage for conducting the flies into the receptacle,the return of the iiies being prevented by cones l1 and 12, disposedapproximately horizontally and con- 6o structed, preferably,ofwire-nettin g but any other suitable material may be employed for thispurpose. The cone 11 is secured to the receptacle at the opening 7, andthe other cone 12, which is arranged within the horizontal casing 8 issecured to a suitable support 13, arranged within the horizontal casing8. The inner end of the horizontal casing is detachably secured to thereceptacle by means of ahinge composed of plates or leaves 7o 14 and 15,provided with registering eyes and receiving a removable pintle'or pin16.7'VV The pin or pintle 16 is adapted to be withdrawn from the eyes ofthe leaves or plates to permit 'the receptacle to be detached. I

The horizontal casing is provided at its outer end with an entranceopening 17, formed in its end wall and in its bottom and receiving aportion of an upright casing 18, constructed of wire-netting or othersuitable 8o material and having an arched or rounded top, and its innerside and outer end are eX- tended below the outer side. The outer end 19of the upright casing is designedl to be placed against the verticalside rail o f the window-sash, as indicated in Fig. 1 of theaccompanying drawings, and the flies ascending the pane of glass ofthe'sash enter the open bottom of the casing 1S and are directed to thesame by an inclined guide 20. The 9o flies are prevented from returningafter they enter the upright casing 18 by means of an upwardlytaperedtrap, 21, constructed of wire-gauze or other suitable material andhaving a closed outer end and provided at its top with a narrow opening.The ilies pass upward through the opening of the trap 21, and as thesides thereof are arranged at an angle to the sides of the casing 18they separate or diverge upwardly from the latter, so roo that iescrawling down the inner surfaces of the side walls of the casing 18 willnot reach the entrance-opening 22 of the trap of the upright casing.

The inclined guide consists, preferably, of

a thin board extending downward at an angle to the adjacent side rail ofthe sash and secured between its ends to the bottom of the receptacle lby means of a thumb-screw 23 or other suitable means and adapted to bereadily detached therefrom when the receptacle 1 is re1noved,asheretofore explained. The upper end of the inclined guide is beveled tofit the lower face of the horizontal casing 8 and is provided with acentral extension 24, projecting into the opening at the bottom of thehorizontal casing and forming a support for an inclined bottom piece 25,of Wire-gauze or other suitable material, which is adapted to consti-ictthe opening of the inner end of the upright casing and which is arrangedat an angle to the bottom of the casing to form a guard for preventingthe return of the ies. The flies ascending the pane of glass of thewindow-sash will be directed to the upright casing by the inclined guideand will pass upward into the said upright casing and enter the same atthe opening 22 of the trap or guard 2l thereof. This will prevent theflies from returning, and they will continue their upward passage untilthey pass through the horizontal casing and enter the receptacle l.

The receptacle l may be detached by removing the screws at the lower endof the supporting-rod 5 and by withdrawing the removable pintle anddetaching the guide 20.

It will be seen that the fly-trap is exceedingly simple and inexpensivein construction, that it is easily applied to a window-casing, and thatit is capable of catching the fiies ascending the pane of glass of thesash and of permitting the flies to be readily removed or destroyed. Thetransparent walls of the receptacle and the horizontal casing and theopenings of the wire-netting form a lighted passage-way through whichthe flies will readily pass.

That we claim isl. A fiy-trap comprising an inclined guide, a casingarranged at the upper end of the guide and closed at the top and one endand open at the bottom and other end, and a receptacle communicatingwith the open end of the casing, substantially as described.

2. A ily-trap comprising an inclined guide, a casing arranged at theupper end of the guide and constructed of wire-gauze and provided at itsbottom and at one end with an opening, a trap or guard arranged withinthe opening at the bottom of the casing, and having sides diverging fromthe sides of the casing, said trap or guard being also provided at itstop with an opening, and a receptacle communicating with the open end ofthe casing, substantially as described.

3. A fly-trap comprising an inclined guard, a casing arranged at theupper end of the guard, and having an open bottom, one of the sides ofthe casing being extended below the other, a trap or guard arrangedWithin the open bottom of the'casing and forming a constricted entrance,anda receptacle communicating with the casing, substantially asdescribed.

4. A Hy-trap comprisinga horizontal casing having transparent walls andprovided at one end with an opening, a guide extending from the openingof the casing, an upright casing communicating with the opening of thesaid casing and provided at its bottom with an opening, and a receptacleconnected with the horizontal casing, substantially as described.

5. A liy-trap comprising an upright easing having an open bottom, ahorizontal casing extending from and communicating with one end of theupright casing, a receptacle connected with the horizontal casing, and aguide connected with the receptacle and with the horizontal casing andsupporting the latter, substantially as described.

6. A fly-trap comprising the horizontal casing provided at one end withan opening, a receptacle communicating with the other end of the casing,an upright casing open at its bottoni and extending into the opening ofthe horizontal casing and provided with an inclined guard, and a guidefor directing the flies to the upright casing, substantially asdescribed.

7. A fly-trap comprising a receptacle having transparent walls, ahorizontal casing eX- tending from and communicating with the receptacleand provided with transparent walls, an upright casing open at itsbottom and communicating with the horizontal casing, and cones arrangedwithin the receptacle and Within the horizontal casing, substantially asdescribed.

In testimony that we claim the foregoing as our own we have hereto aixedour signatures in the presence of two witnesses.
